Time out against someone’s will is nothing like a freely-chosen relaxing time out, and it is dishonest to use one term for the two opposite things.
One of our best theories (the framework theory of evolution) is not scientific, but that it is none the worse for that. And all scientific theories rely on a philosophical framework.
The ‘Don’t children prefer strict rules so they know where they stand’ argument is based on an equivocation between two meanings of the word ‘strict’, namely (1) harsh, coercive, and (2) well-defined, precise. People do like to know the rules under which they are living, i.e. they want strict(2) rules. But they do not like getting hurt, so they do not want strict(1) rules.
Many have suggested that my use of the word ‘coercion’ is non-standard and that I should find another word, but I think that is the quest for a euphemism. People don’t like using a harsh word for something they think is morally right. But if you prefer, use the word ‘manipulation’ instead—as long as it is clear that manipulating children is not taking them seriously either.
